This invention relates to hinges and pai'- ticularlyto what are known ascovered joint hinges wherein the. separate butts of the hinge arefashionedfroni rsheet metal; and the object ofV the invention, is toprovide a hinge of the classz-specied, one of the butts of which isformed from a strip of sheet metahone end vportion of said strip Vbeingfashioned to form a hook-shaped end portion and a knuckle withinthehook-shaped end portion whereby said knuckleforms the piv-r ot portionof saidbutt and the hooleshaped portionV thereof forming ahood forpartially closing the rpivotfportion of the butt; a further object beingto provide a hingev of the class described, one of the butts of whichisfashioned from sheet metal and the end portion thereofbeing curved andfashioned to form a hood having top and Vbottoni walls, and a pintlebearingwithin said hook-shaped end portion a still further object of theinvention being to materially simplify the construel tion of a hinge ofthe class under consideration whereby the manufacturing costs arereduced and astrong .and durable hinge produced; and with thesev andother objectsvin view, theinventionconsists in a hinge of the.

class specified 'and in the improved method of producing the samehereafter more specificald ly set out inthe specification and claims.

The invention described and claimed here.

inl constructing the hinge. from` saidblanlg" thecornerportions at oneend thereofare cut out as indicated in dot and dash lines at 11 Vin Fig.2er' the drawing, leaving at said end n portion a projecting tonguemember 12 of.

I '9i The next step in theformation ofthe .hinge butt. consistsinarranging-the curved end portion 13 `intdposition to facilitate thefashioning of said end portion into'predetermined formation, whichresult maybe readily accomplished bv the angularfposi-4 tioning of theshank ofthe blank thus formed as indicated in fullandl dottedlinesinFig. 4 ofthe drawing. By' means Tofsuitabledies, the curved end fportion 13 as well` as` the 'whichis a pintlef bearing 16, the hingebeing recessed kat the opposite sides-ofthepintle y bearing as shown at17 to receive the kniieliles 'or pintle bearings ythe other part'orbi'itt vtongue member 12 is .swaged or compacted to Y. form thereof acurvedhoodportion'll Within `4 the hinge; the above result beingproduced by dies VWhich depress the shoulder portions 14 and curved endportion 13 of the blank when positioned substantially as showny in Fig.1l to force the metal into position to form.. comparatively thin Walls18 at the opposite sides of the bearing 16 which constitute part of thehood, said Walls V18 gradually increasing.

'It Will be' understoodthatf with the construction shoWnin: Figs. 1'to 7inclusive, that'. the knuckles or bearing Qtjoflthe hinge' butt .25are-exposed through the top and-fbottoin faces of the hinge (note Fig.41 ofthe Vdrawto form av covered joint hinge; However, in

Fig V8 of the drawing I Vhavefshown armodi# fication in Which' the topand bottom faces of the knuckles-28am. closed by Walls 26 formedintegral With the blank 1()` orintegral with the curved endportionofsaid blank and one of tliesewalls is-shoWn inf said figure, andthesew'alls are apertured asshown. at 27 to receive the pintle `pin 23,'and thesapertures 27 f mayc-pen outwardly through the Walls v26 asindicated at 28' Whichfacilitates Vthe Vcuttingofthe apertures 27 whichareangul'ar' particularlyin one of the Walls Q6 to re! v cci-ve threangularshank or portion of' a pintle pin to prevent the rotationv ofsaid pin in the hinge butt formed from the blank 10. It Will beunderstood lio-Wever, that I am'notn'ecessarily limited tothe specificformation ofthe 'aperture27 herein set out, nor-am I limited -to thespecific shape or form of the: curved end orhoodr portioniof the hingebutt, andthe pintlebearing Within said hood portion, and variouschangesin and modifications of the construction herein shown and described andthe method herein shovvn and described and the method herein set out maybe made, Within the scope of the appended claims, Without departingyfrom the spirit of my invention or sacrificing its advantages.

It :will be iapparent Ythat in the finish trimming, sizing and shapingof the hinge butt fashioned fromthe blank 10, the top andbottom-facesfof the pintle-bearin'gl maybe iinisheda'nd brought `topredetermined spaced relation toreceive the other butt of the/hinge, andthe'recessesxl? cleanedout if necessary to provide the free action oftheseparate butt members one-'upon another.
